2o claims (oreal-41.3)

. which grease lubricant or other similar material may be packaged rfor sale and distribution through the usual channels of commerce and from which the lubricant, grease or other material may then be expelled under suitable pressure directly into the transmission or. differential housing of the automobiles, and such other machine parts where the lubricant is required, without first transferring the contents of the tin can into some other vesselforming a part of some dispensing apparatus.

A further object of my invention is to provide simple and inexpensive means whereby the contents of the tin can may be expelled and the 5 tin can destroyed thereby or rendered unfit for subsequent use as a container.

With the above and other 'objects in view, my

invention consists of a container including a generally cylindrical or prism-atie body or a body having a generally cylindrical prismatic or other suitable parallel side walls, a top and bottom secured to said body, an opening in said topand means for forcing said bottom inwardlyy and through vthe body in the fashion of a piston, thereby to help to expel the contents of the can through the opening at the opposite end` or top of the can.

My invention further consists of other novel features and' details of construction, all of which will appear more fully from the following de# tailed description and accompanying drawing.

For the purpose of illustrating my invention, I have shown in the accompanying drawing forms thereof which are at present preferred by me,

since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumen. talities of which my invention consists can be variously arranged and organized,v and ,that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

, According to one embodiment of my present invention, I provide an original container -of sheet metal or the like, designated generally by the numeral I, of any suitable cross-section which is generaly constant throughout its length, 35

but preferably of a circular cross-section. 'I'he container i includes the generally cylindrical side Wall 2, the top end member 3, seamed thereto by any suitableinterlapped seaml, or other suitable' seam of any suitable or conventional con- 40 struction, and the bottom end member 26 seamed to the opposite end of the cylindrical side wall 2 along an interlapped 'seam 'i of any suitable or conventional construction. These opposite end members 3 and 26 are thus preferably perma- 45 nently interlocked with the cylindrical side Wall 2 along the annular lapped seams I or 1, in contradistinction to being frictionally held in place through the frictlonal engagement of generally parallel annular zones.

'Ihe ejector, designated generally by the numeral 42, is of the general type disclosed in copending application Serial No. 705,562, filed January 6, 1934, which matured into Patent No, 2,125,2 58 on July 26, 1938, and in co-pending ap- 55 vision, and includes a can gripper portion andl a ram rod and actuating means therefor, in operative relation to the can gripper portion. Thus the ejector 42 includes a main body portion 43, of

more or less circular cross-section, having a stationary bead-engaging member 44, o! more or less arcuate shape and integrally formed therewith, or otherwise flxedly related thereto, and a movable bead-engaging member 45 at a point more or less diametrically opposite to the bead-engaging member 44. The movable bead-engaging member 45 may be pivoted at 46, to any suitable webbing or other structural member or portion 41 of the body 43 (being either integral ably held in an engaging position by any suitable spring 48. The members 44 and 45 are.

adapted to engage the slight annular bead-like seam 1 surrounding the bottom of the can, thereby to hold the can fast and in predetermined relation to the ram rod 49, and the follower plate or press platen 21, which is suitably secured to the ram rod 49, as for instance by screw-threaded connection or by means of a rivet or by other suitable fastening means. In the embodiments of my invention herein shown, the ram rod 49 is provided with a series of spaced annular grooves 58 generally throughout its length, with the exception of the innermost terminal portion thereof, to which the plate 21 is secured.

The annular grooves 50 include the more or less plane annular surfaces 5|, generally at a right angle to the axis ofthe rod 49 and the inclined and more or less conical surfaces 52, thereby forming a rack which may be advanced positively in one direction (in the direction of the arrow I3) by means of the spring-tensioned pawl |33, and the rod 49 may be rotated without affecting the function andoperation of the pawl |33. The rod 49 is slidably mounted within Ya suitable bore 54, of the guide portion 55 of the body 43, which is preferably integrally or otherwise iixedly related to the body portion 43. A stationary handle 56 extends generally parallel to the ram rod l49 (shown broken away in the drawing), and is either formed integrally with the body portion 43 or is otherwise firmly or xedly secured thereto or to the web portion 41. The handle 56, extending generally parallel to the ram rod 49 in closely spaced relation thereto, may be slightly dished in cross-section, so that the ram rod 49 may lie generally within the dished groove of the handle, thereby to afford the ram rod more protection against injury in handling. The movable handle 58 is preferably pivoted to the member 43,'as for instance by means of the pivot 59, extending through said handle 58 and through the pivotal lug or hinge member or portion 68, which is also integrally or otherwise fixedly or stationarily related to the body portion or member 43. In suitable spaced relation to the pivot point 59, the pawl |33 is pivotally secured to the handle 58 by means of the pivot pin |34. The pawl |33 is yieldably urged towards theram rod by any suitable spring, such as the helical compression spring |35 (see Figure l) while the set screw |36 adjusts the limiting position of the pawl |33 in relation to the handle 58. Thus, when the handle 58 is in the completely retracted position (deflected in the direction of the arrow |31) the pawl |33 will be clear of the rod 49, so that the rod may be pulled back or lretracted. The spring |38 serves to open or to retract the handle 58. The spring-pressed plunger |39, urged by the spring |48, serves yieldably to retain the rod 49 in any position.

In the normal use of the device o! my present invention, the can is placed in operative position between the bead- engaging members 44 and 45, as indicated in Figure 1. Thereupon the two handles 56 and 58 are grasped ln one hand and by a one-handed operation, to wit, the opening and closing of the hand, the handle 58 is oscillated to and fro about the pivot 59, thereby causing the pawl |33 to ride idly over each notch of the rod 49, while the handle 58 is moved in the direction of the arrow |31, and causing the pawl 33 firmly to engage in the next notch of the rod 48 when the handle is moved in the opposite direction, and to advance the rod 49 and the plate 21 in the direction of the arrow I3 to the extent of one or more notches.

In Figures 1 and 2, I have illustrated a form of my invention, wherein the can bottom 26 may be fastened directly to the cylindrical body 2 of the container, having within it a packing gasket I4 formed of any suitable material such as cardboard, pasteboard, rubber or rubber composition. The ram rod 49 is provided with a follower plate 21, and an annular sheet metal cutter 28, having a series of generally annularly arranged, inwardly bevelled cutting edges 29, which meet at points 30 which are adapted first to penetrate the bottom of the can, thereby to lessen the force required to cut the bottom of the can out in a generally annular formation. These surfaces 29 may either be curved, or may be alternately inclined surfaces, as indicated in Figure 6. A packing gasket of suitably resilient or expansive material, 3|, may be provided between the generally annular cutter 28 and the plate 21, to augment the packing action of the disc I4.

In order to permit the cutter 28 to more nearly approach the cylindrical body 2 of the container, the bead, designated generally by the numeral 1 may be off-set slightly in an outward direction, as indicated particularly in Figure 9, so that the outer diameter of the cutter 28 may be such as more or less snugly to fit within the inner diameter of the cylindrical body of the can, thereby to serve as a piston as well, in the ejection of the contents of the can.

In Figures 1, 3, 5, 7 and 8, I have illustrated another feature in connection with the top of the container, which I may apply to a container having the form of bottom shown in Figures 1. 2 and 9.`

In this phase of my present invention, the top 3 of the can is without the conventional screwi threaded neck which detachably carries a screwcap, and instead is provided merely with a central hole 6|, which may be produced by providing a circular scoring in the top 3 of the can which may be punched out by any suitable implement to form the opening 6|, and may be covered (while the container is in storage-or in transit, orotherwise unusued) by Ia tin disc soldered in spots to the outside of the top and having a suitable pull-tab by means of which it may be torn off from the top in the conventional manner'of sealing discs, or in the general manner of the soldered sealing member 38 shown in Figuresv 1 and 5 of co-pending application Serial No. 705,562 filed January 6, 1934, but merely in a at form. The top bead 4 in this phase of my invention is provided with two, three, or more indentations 32, which are pressed in by any suitable forming die. A generally disc-like closure member or attaching member 33 is provided, having a central opening into which or to which a spout 35 is secured, and having an outer ilange 31 adapted to surround the bead l, and having two, three or more inwardly projecting. clawlike hooks 38 which are adapted to pass through the notches 32 in the upper bead 4 of the can, and which may then be caused to engage the bead by a slight turning. or a slight rotation of the member 33, thereby causing an interlocking between the member 33 and spout 35 and the can, the end portion 62 of the spout 35 being projectable through the container wail 3. The circular scoring in the container wall 3 at the discharge end of the container (indicated particularly in Figure 7 by the small central dotted circle) facilitates the projection of the spout 35 through the end wall 3 at the discharge end of the container I, by forming a weakened circulax-.line defining a potential discharge opening which may be formed by any suitable means, as hereinabove mentioned.. A suitable resilient or expansive annular packing gasket 39 may be provided within the annular flange 31, as indicated particularly in Figures 3 and 8, adapted to contact the bead 4, thereby to make a rmer seal against the passage of fluid through the hole 8| and through the spout 35.

I am aware that my invention may be embodied in other specific forms without departing from the spirit or essential attributes therel of, and I therefore desire the present embodi ments to be considered in all respects as illus-' trativeand not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
